Korea Telecom announced that it will be relying on the scalable R&S TS8980 RF test system and the R&S CMW500 wideband radio communication tester from Rohde & Schwarz to ensure the smooth rollout of the carrier’s 4G mobile radio.
The two companies have signed a long-term LTE cooperation. KT uses the R&S TS8980 in the test lab to perform transmitter and receiver tests on LTE-capable user equipment.
The system also supports radio resource management (RRM) tests, which aim at utilizing radio resources more efficiently. Existing LTE resources are only made available when users actually require them. Resources must frequently be reallocated because bandwidth utilization varies heavily.
KT uses the R&S CMW500 wideband radio communication tester for RF and protocol tests on LTE user equipment. These measurements are made in the signaling mode. In signaling tests, the devices under test (DUTs) are examined in the future network under near-real conditions. Especially when introducing new technologies such as LTE, this procedure helps to avoid risks. The R&S CMW500 also supports the measurements required for smooth handover between the LTE infrastructure and the existing W-CDMA infrastructure.
Rohde & Schwarz and Korea Telecom have been partners for years. Korea Telecom deploys Rohde & Schwarz test and measurement equipment in its W-CDMA networks.
